The "Vikings Season 4" is already starting its production and several speculations on what's in store for season 4 are already proliferating online. Floki's death by Ragnar is something to look forward to in the premiere of the new season. Latherga's redemption of her Earlhood from Kalf is also expected for the newest season of the TV series.

"Vikings Season 4" production is already on the go and several interesting plot predictions on the upcoming season are already making rounds online. One of the interesting plot predictions for the coming season is the building tension between Ragnar and Floki, a friendship scared by Athelstan's death that could lead to Floki's death in the hands of Ragnar. Meanwhile, after successfully helping Ragnar seize Paris, Lagertha's pursuit to redeem his Earldom from Kalf might actually take place in the upcoming episodes of Season 4.

The "Vikings" successfully raided Paris in the last episode of Season 3 after Ragnar Lothbrok successfully faked his death. His scheme may have led them to victor against the Paris army but revealed shocking truths about the past that he was not prepared for. Athelstan murderer finally revealed himself and was nonetheless but Ragnar's trusted friend, Floki. This revelation might actually bring death for Floki in the upcoming "Vikings Season 4" as the tension between Floki and Ragnar increases.

Meanwhile Rollo chose to stay on Paris as Ragnar and his army sails back to Kattegat. Emperor Charles offers land and his brave daughter Gisla to Ragnar's brother, in exchange of his loyalty to Ragnar. Will Rollo choose his brother or will a woman come in between them? Sibling rivalry is also something to look forward to in Season 4.

Season 3 on the other hand marked Bjorn's capabilities to lead the Vikings Army. He was the one who conspired with his father in faking his death and led their Army to the gates of Paris. He is one of the biggest characters to look forward to in the upcoming "Vikings: Season 4."

Lagertha have proven herself as a warrior once more and has time in her hands to get back to Hedeby to claim her Earldom from Kalf. It would be very exciting to see Latherga in "Vikings: Season 4" ruling the settlement once more. In Season 2 of the series, Lagertha killed her second husband Ear Sigvard after being abused since their marriage. Kalf usurped her position after being busy working on Wessex and helping Ragnar in his cause. Lagertha promised to kill Kalf to get her earldom in season 3, hopefully, this will push through with the premiere of the "Vikings: Season 4."

Battles, brotherhood, death and a marriage are just some of the things to look forward to in the upcoming release of "Vikings: Season 4" later this year, 2015 in the History Channel.
